Yes it is possible. But the current kernels have a driver limit of 6. It is easy to increase this limit,I by adding more major numbers (each IDE interface (drive pair) requires a major number).
Create the new majors: IDE6_MAJOR, IDE7_MAJOR, .. as many as needed. Then just grep for all occurances of the existing IDE5_MAJOR in linux/drivers/block/*.[ch], and add equivalent code/entries for the new MAJORs.
Recompile and reboot. Presto.
